A pkg body with variables global to subprograms in the pkg is considered a pkg
with state, and the variables represent that state. As such they are often
referred to as state variables rather than global.

You can't access anything from a file. Do you mean from code that uses the pkg
as a client? Things in pkg bodies cannot be accessed by anything outside the pkg
body.

I'm not clear what "this way" refers to. You could move the variable to the pkg
spec and it could be accessed by clients there, but that would be A Very Bad
Idea. Variables in pkg specs are the root of all evil (or at least the cause of
horrible, impossible-to-understand code).
